Solution Overview

Problem

Existing payroll systems face inaccuracies when calculating working hours beyond 24:00, require detailed input data, and are inefficient without expert guidance, leading to potential budget overruns and legal compliance issues.

Innovation Solution

A salary management device and method that uses a circular reference function to automatically allocate salaries into categories based on user-inputted total salary and overtime from numerically formatted working hours, converting digital clock-in and clock-out times into numerical format, and assessing compliance with labor laws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If digital clock-in and clock-out times are used to calculate working hours, then time recording is convenient, but calculation accuracy deteriorates when working hours exceed 24:00

Engineering Contradiction:
Improvetime recording convenienceVSAvoidworking hours calculation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces an intermediary conversion process that transforms digital time format (HH:MM) into numerical format representing actual working hours. This intermediary step resolves the contradiction by enabling accurate calculation of overtime hours while maintaining the convenience of digital time recording. The conversion unit acts as a mediator that translates convenient digital inputs into precise numerical outputs for salary calculation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If detailed input data such as working hours and days worked are required for payroll calculation, then verification accuracy improves, but system complexity and setup time increase

Engineering Contradiction:
Improvepayroll verification accuracyVSAvoidsystem setup complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-converting digital time data into numerical working hours before the payroll calculation process. This preliminary conversion prepares the data in advance, eliminating the need for complex real-time calculations and reducing setup complexity. The working hours are predetermined and stored in numerical format, ready for immediate use in salary calculations without requiring complex verification procedures.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If traditional payroll software is used without expert guidance, then implementation speed increases, but compliance accuracy with labor laws decreases

Engineering Contradiction:
Improveimplementation speedVSAvoidlabor law compliance accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements self-service by incorporating automated compliance verification functions directly into the payroll system. The system automatically checks converted working hours against labor law standards and provides compliance assessments without requiring external expert guidance. This enables quick implementation while maintaining high compliance accuracy through built-in verification mechanisms.

Inventive Principle:
Principle #25Self-service

AI summary

A salary management device and a method therefor are disclosed. The present invention allows salaries to be automatically distributed by wage category by using a circular reference function on the basis of total salary according to user input and extended hours according to work hours in an automatically converted numeric format, and thus the salaries can automatically be distributed by wage category within a range not exceeding the total amount of monthly salary inputted by the user, so that the monthly salary amount initially expected by the user cannot be exceeded, the resulting value can be checked in real time so that the user can set work hours and salary as desired, the program setting time is shortened, and the user can self-set without expert help.
